BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a cover mountable to a beveragecontainer and a mounting method and apparatus thereof, and moreparticularly, the present invention relates to a cover mountable to abeverage container and a mounting method and apparatus thereof, whereinthe cover is mounted to an upper surface of a container end which iscoupled to an upper end of the beverage container and on which a pulltab is installed to be used when opening a discharging hole defined inthe upper surface of the container end, in a manner such that the covercan selectively close and open the discharging hole in a state that thedischarging hole is initially opened.

[0003] 2. Description of the Related Art

[0004] Conventionally, a metal can is widely used as a beveragecontainer throughout the world in view of its portability andstorability. In general, the metal can is, as shown in FIG. 1, made ofaluminum or a thin plate which is coated with aluminum. In itsconstruction, the metal can comprises a body 10 which is formed to havea cylindrical configuration so that a beverage is accommodated therein,and a container end 20 which is coupled to an upper end of the body 10.

[0005] The container end 20 is formed with a discharging hole 22 throughwhich the beverage can be discharged out of the 22 is installed on thecontainer end 20. The capping device is composed of a seal plate 24 awhich is integrally formed with the container end 20 upon forming thecontainer end 20 to close the discharging hole 22, and a pull tab 24 bwhich is securely installed on an upper surface of the container end 20by a central pin 26 in a manner such that it can depress downward theseal plate 24 a to result in pivoting movement of the seal plate 24 ainto the interior of the beverage container.

[0006] However, in the metal can constructed as mentioned above, oncethe discharging hole 22 is opened, it is impossible to reclose thedischarging hole 22. Therefore, in the case that a period of time islapsed in a state wherein the beverage container is opened, foreignsubstances can enter into the beverage container to contaminate abeverage accommodated therein. Also, if a user moves while holding thecan in his hand, the likelihood of liquid spillage from the beveragecontainer is increased.

[0007] To cope with these problems, U.S. Pat. No. 4,717,039 discloses acontainer cover which is integrally and rotatably coupled to an uppersurface of a beverage container by a central pin and has a sealdepression, a straw insertion hole and a finger grip; and U.S. Pat. No.4,852,763 discloses a beverage container cover which is detachably androtatably coupled to an upper surface of a beverage container and isformed with a notch.

[0008] However, the U.S. Pat. No. 4,717,039 still suffers from defectsin that the container cover is integrally coupled to the upper surfaceof the beverage container. Therefore, because the container cover mustbe necessarily coupled to the beverage container upon manufacturing thebeverage container, a separate assembling process is required and theconstruction of an existing beverage container should be modified.Specifically, since the container cover cannot be detached from thebeverage container, the container cover cannot but be a permanentfeature of the beverage container and, as such, it cannot be removed orreused. In this regard, due to the fact that the container cover cannotbe removed from the beverage container, it is impossible for a user tosee a lower surface of the container cover, and thus, the containercover cannot be effectively used for other purposes, such as a gameimplement or a medium for providing free gifts.

[0009] While the U.S. Pat. No. 4,852,763 can solve more or less thedefects induced in the U.S. Pat. No. 4,717,039, due to the fact that thecontainer cover is detachably coupled to the upper surface of thebeverage container, it also encounters a problem in that the containercover is only formed with the notch which can be selectivelycommunicated with a discharging hole of the beverage container.Consequently, since additional convenience factors such as a strawinsertion hole through which a straw can be inserted into the beveragecontainer, a finger grip or the like are not provided, a higher grade ofsatisfaction cannot be rendered to a user. Further, in both of the U.S.Pat. Nos. 4,717,039 and 4,852,763, if a lengthy period of time is lapsedwhile the beverage containers are circulated in the market in a statewherein the container cover is mounted to each beverage container,because potentially hazardous debris such as dust particles may beaccumulated on an upper surface of the container cover, the debris canenter into the human body, whereby health conditions of the user can bedeteriorated.

[0010] Also, because the straw insertion hole of the U.S. Pat. No.4,717,039 is formed to have a predetermined diameter, in the case that adiameter of a commercially available straw does not correspond to thepredetermined diameter of the straw insertion hole, the straw can playor float on the beverage rather than being fixedly maintained in place.In addition, in the case that a diameter of a commercially availablestraw corresponds to the predetermined diameter of the straw insertionhole, because the straw is inserted through the straw insertion hole ina vertical direction, a drinking angle of the straw cannot be easilychanged, whereby a problem is caused in that the user must drink thebeverage while tipping the beverage container.

[0011] On the other hand, in order to open the discharging hole 22 ofthe beverage container, while the pull tab 24 b must be pulled upwardthereby to depress the seal plate 24 a downward, at this time, becausethe pull tab 24 b is brought into nearly close contact with the uppersurface of the container end of the beverage container, a fingernail ofthe user is likely to be broken or damaged in the course of pullingupward the pull tab 24 b, whereby troublesomeness is caused in that thepull tab 24 b cannot be easily pulled upward.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0033] Reference will now be made in greater detail to a preferredembodiment of the invention, an example of which is illustrated in theaccompanying drawings. Wherever possible, the same reference numeralswill be used throughout the drawings and the description to refer to thesame or like parts.

[0034]FIG. 2 is a perspective view illustrating a container cover inaccordance with an embodiment of the present invention;

[0035]FIGS. 3a through 3 d are schematic plan views illustrating stateswherein the container cover according to the embodiment of the presentinvention is used; and

[0036]FIGS. 4a through 4 r are views illustrating container coversaccording to several variations of the present invention.

[0037] As can be readily seen from FIG. 2, a beverage container 100 isformed, on an upper surface thereof, with a discharging hole 124 throughwhich a beverage accommodated in the beverage container 100 can bedischarged out of the beverage container 100. The beverage container 100has a capping device. The capping device comprises a seal plate and apull tab 122. The seal plate is formed in a manner such that it closesthe discharging hole 124 when the discharging hole 124 has not yet beenopened. The pull tab 122 is coupled to the upper surface of the beveragecontainer 100 in a manner such that it can depress downward the sealplate to let the seal plate break free along a scored line which isformed around the seal plate. According to the present invention, acontainer cover 130 is provided in a manner such that it is mounted tothe upper surface of the beverage container 100 thereby to selectivelyopen and close the initially opened discharging hole 124.

[0038] The container cover 130 is rotatable installed on the uppersurface of the beverage container 100. The container cover 130 comprisesa body which is formed to have, substantially a disc-shapedconfiguration. By the fact that the body is partly cut away from an edgetoward a center thereof, the container cover 130 is formed with abeverage discharging opening 132 which has a predetermined width and apredetermined contour. An inner end of the beverage discharging opening132 is delimited by a rotation guiding part 132 a which has apredetermined curvature to guide rotation of the container cover 130.The container cover 130 has an advertisement surface 138 which isdefined on an upper surface of the body having the disc-shapedconfiguration. The advertisement surface 138 has a predetermined area ina manner such that an advertising design or letters can be printed or anattachment can be affixed thereon.

[0039] The container cover 130 can selectively include a plurality offiltering holes 134 and a straw insertion hole 136. The plurality offiltering holes 134 are defined at a predetermined region on the uppersurface of the body of the container cover 130 to have a predeterminedcontour, in a manner such that they can filter solid matters existing inthe beverage container 100. The straw insertion hole 136 is also definedon the upper surface of the body of the container cover 130 to have apredetermined diameter, in a manner such that a straw can be insertedtherethrough.

[0040] While the beverage discharging opening 132 has substantially ashape of an isosceles triangle wherein a width is gradually decreasedfrom an entrance corresponding to a circumferential outer surface of thecontainer cover 130 toward the rotation guiding part 132 a, it is notlimited to the shape of an isosceles triangle and instead, can bediversely varied in its shape. For example, as shown in FIG. 4a, thebeverage discharging opening 132 can be formed with a bulged part 132 bwhich has a preset curvature in a manner such that the beveragedischarging opening 132 has the same contour as the discharging hole 124of the beverage container 100 thereby to enable a front end of the pulltab 122 to easily depress the seal plate.

[0041] While it is preferred that the advertisement surface 138 isdefined on a portion of the upper surface of the body of the containercover 130 to have the predetermined area, which corresponds to a leftside or a right side of the beverage discharging opening 132, withoutadversely affecting forming positions of the beverage dischargingopening 132, the plurality of filtering holes 134 and the strawinsertion hole 136, the advertisement surface 138 can be defined at avariety of locations. Also, diverse advertising methods such asprinting, affixing or forming can be effected on the advertisementsurface 138.

[0042] While the plurality of filtering holes 134 can be formed in amanner such that they are composed of a plurality of slots which extendin a vertical direction and have different lengths and such that theplurality of slots are spaced apart one from another by a predeterminedspacing, they are not limited to this arrangement, and for example, theplurality of slots can extend in a horizontal direction and a pluralityof holes which have a predetermined inner diameter can be spaced apartone from another by a predetermined separation.

[0043] The straw insertion hole 136 can be formed in a manner such thatit has a variety of diameters depending upon a diameter of a particularstraw which is used in the beverage container 100.

[0044] On the other hand, as shown in FIG. 4a, a plurality ofprotuberances 140 are formed on the upper surface of the body of thecontainer cover 130 or allowing a user to easily apply rotating force tothe body of the container cover 130.

[0045] In this connection, a single protuberance can be projectedlyformed on the body of the container cover 130, or the plurality ofprotuberances 140 can be projectedly formed on the body of the containercover 130 in a manner such that they are spaced apart one from anotherby a predetermined distance. The single protuberance or the plurality ofprotuberances 140 can be formed at a predetermined region on the body ofthe container cover 130, without adversely affecting forming positionsof the beverage discharging opening 132, the advertisement surface 138,the plurality of filtering holes 134 and the straw insertion hole 136.Also, while, in the present invention, the plurality of protuberances140 are projectedly formed on the body of the container cover 130, aperson skilled in the art will readily recognize that the plurality ofprotuberances 140 can be depressedly formed on the body of the containercover 130.

[0046] As shown in FIG. 3a, in a state wherein the aforementionedcontainer cover 130 is mounted to the upper surface of the beveragecontainer 100 of which the discharging hole 124 is opened, if the userpulls upward the pull tab 122 in order to drink the beverage, the sealplate (later, described as a “discharging part”) breaks free along thescored line which is formed therearound while pivoting downward, wherebythe discharging hole 124 is defined. In this state, when the user drinksthe beverage, the beverage is discharged out of the beverage container100 through the beverage discharging opening 132 which is arranged to becommunicated with the discharging hole 124.

[0047] If the user moves to a certain place while holding in his handthe beverage container 100 laden with still-unconsumed beverage or it isnecessary to interrupt drinking of the beverage and leave the beveragecontainer 100 laden with still-unconsumed beverage in a moving vehicle,as shown in FIG. 3b, by rotating the container cover 130 to cause aclosure surface which is defined at a side of the beverage dischargingopening 132, to close the discharging hole 124, it is possible toprevent some gaseous ingredients contained in the beverage from beingdischarged into the atmospheric air and foreign substances suspended inthe atmosphere from entering into the beverage container 100. Further,it is possible to inhibit spillage of the beverage even when thebeverage container 100 is overturned.

[0048] Also, for example, in the case that a beverage which is made bygrinding vegetables and fruits is accommodated in the beverage container100 so that solid matters exist in the beverage, if the user does notwant to drink the solid matters existing in the beverage, as shown inFIG. 3c, the container cover 130 is rotated so that the plurality offiltering holes 134 are positioned above the discharging hole 124. Bydoing this, when the user drinks the beverage, the solid matters arefiltered by a filtering part which includes the plurality of filteringholes 134, and only liquid beverage is discharged through the pluralityof filtering holes 134, whereby it is possible to suit the user's taste.

[0049] Further, even in the case that a child wants to drink thebeverage using a straw, as shown in FIG. 3d, by rotating the containercover 130 so that the straw insertion hole 136 is positioned above thedischarging hole 124, the straw can be inserted into the beveragecontainer 100 through the straw insertion hole 136 and the discharginghole 124.

[0050] In the meanwhile, as shown in FIG. 4a, in a structure in whichthe plurality of protuberances 140 are formed on the upper surface ofthe container cover 130, since rotating force can be easily transferredto the container cover 130, the rotation of the container cover 130 canbe implemented in an easier manner. Also, as can be readily seen fromthe same drawing, in a structure in which the bulged part 132 b isformed in the beverage discharging opening 132, because the front end ofthe pull tab 122 of the capping device can easily depress the seal platethereby to open the discharging hole 124, even in the case that thecontainer cover 130 is mounted to the beverage container 100 before thedischarging hole 124 is opened, the discharging hole 124 can be easilyopened by pulling upward the pull tab 122.

[0051] On the other hand, as shown in FIG. 4b, the container cover 130is configured in a manner such that a connecting part 132 c is formedalong a portion of the circumferential outer surface of the containercover 130, which corresponds to an outer end of the beverage dischargingopening 132, thereby to close the outer end of the beverage dischargingopening 132. According to this, by the closing function of theconnecting part 132 c, it is possible to prevent foreign substances fromaccumulating on an inner edge portion of a container end 120. Also, upondrinking the beverage, because the lip is brought into contact with anupper surface of the connecting part 132 c, uncomfortableness which canbe induced to the user due to contact with the sharp edge portion of thebeverage container 100, can be avoided.

[0052] In addition, as shown in FIGS. 4c and 4 d, the container cover130 is configured in a manner such that a film member 136 a is providedin the straw insertion hole 136 in a manner such that it closes thestraw insertion hole 136 and is torn when the straw is inserted throughthe straw insertion hole 136. Hence, it is possible to prevent foreignsubstances from accumulating on the upper surface of the beveragecontainer 100 through the straw insertion hole 136. Upon drinking thebeverage using the straw, when the film member 136 a is torn by an endof the straw and the straw is inserted through the straw insertion hole136, because the torn film member 136 a is squeezed against acircumferential outer surface of the inserted straw, the straw isprevented from playing or floating in the beverage, whereby it ispossible to conveniently drink the beverage.

[0053] In the meanwhile, as shown in FIGS. 4e and 4 f, the containercover 130 is configured in a manner such that a protective tape 138 a isremovably attached to the upper surface of the container cover 130. Theprotective tape 138 a serves to prevent foreign substances from directlyadhering to the upper surface of the container cover 130. Further, asshown in FIGS. 4g and 4 h, the protective tape 138 a can be formed tohave a contour which is similar to that of the beverage dischargingopening 132 so that it can close only the beverage discharging opening132. Also, the protective tape 138 a can be modified to have a varietyof shapes. Also, as shown in FIG. 4i, the protective tape 138 a can beremovably attached to the entire upper surface of the container cover130, and dotted cut lines 138 c are formed on the protective tape 138 aselectively around the beverage discharging opening 132, the strawinsertion hole 136 and the plurality of filtering holes 134, therebyenabling the user to selectively and partially remove the protectivetape 138 a as occasion demands and use the correspondingly exposedopening or hole.

[0054] Moreover, a removal tab portion 138 b is provided in an edgeportion of each piece of the protective tape 138 a, which isindependently removed from the entire protective tape 138 a, therebyallowing a protective tape removing operation to be smoothly performedupon drinking the beverage.

[0055] In the mean time, referring to FIGS. 4j and 4 k, there are shownperspective views illustrating another straw insertion structureaccording to the present invention. As shown in FIGS. 4j and 4 k, in thevicinity of the beverage discharging opening 132 of the container cover130, a straw supporting member 137 is formed by the fact that a portionof the container cover 130 is cut. The straw supporting member 137 isconfigured in a manner such that it can be folded at a predeterminedangle to be positioned above the beverage discharging opening 132.

[0056] The straw supporting member 137 comprises a supporting part 137 awhich has substantially a rectangular configuration and a strawinsertion part 137 b which has substantially an annular ring-shapedconfiguration. The supporting part 137 a has one end which adjoins thebeverage discharging opening 132 of the container cover 130. The one endof the supporting part 137 a is integrally formed with the body of thecontainer cover 130 in a manner such that it can be folded from a planeof the container cover 130 along a dotted cut line at a predeterminedangle. The supporting part 137 a has the other end which is formed as afree end. The straw insertion part 137 b is integrally formed with theother end of the supporting part 137 a in a manner such that it can befolded from a plane of the supporting part 137 a along a dotted cut lineat a predetermined angle. A straw insertion hole 137 c is defined in acenter portion of the straw insertion part 137 b to have a predetermineddiameter in a manner such that the straw can be inserted therethrough.

[0057] Also, a semi-circular groove 137 d is defined at a portion of thecontainer cover 130, which defines the straw supporting member 137 insuch a manner that it faces the other end of the straw insertion part137 b, thereby to allow the straw supporting member 137 to be easilyseparated from the body of the container cover 130.

[0058] In a state wherein the straw supporting member 137 is configuredas shown in FIG. 4j, if the user wishes to use the straw supportingmember 137, as shown in FIG. 4k, a fingernail or the like is firstinserted into the semi-circular groove 137 d. Then, the supporting part137 a is folded at the predetermined angle and thereafter, the strawinsertion part 137 b is folded at the predetermined angle. Thus, in astate wherein the straw insertion part 137 b is positioned above thebeverage discharging opening 132, the straw is inserted through thestraw insertion hole 137 c to enable the user to drink the beverageusing the straw. At this time, by altering the folding angles of thesupporting part 137 a and the straw insertion part 137 b of the strawsupporting member 137 to angles which are adequate for the user to drinkthe beverage, it is possible to easily drink the beverage accommodatedin the beverage container 100, without experiencing any inconvenience.

[0059] On the other hand, referring to FIGS. 4l through 4 p, means forpreventing the fingernail of the user from being broken or damaged inthe course of pulling upward the pull tab 122 for opening thedischarging hole 124 of the beverage container 100, is provided to thecontainer cover 130 which has the beverage discharging hole 132 and theplurality of protuberances 140, thereby enabling the discharging hole124 to be easily opened. Two groups of protuberances 140 a and 140 b areformed on the container cover 130 leftward and rightward, respectively,of the beverage discharging opening 132 for rendering rotation of thecontainer cover 130. In the case that the container cover 130 is mountedto the metal can serving as the beverage container, a pair of tablifting projections 135 for slantingly lifting the pull tab 122 at apredetermined angle upon rotation of the container cover 130, are formedat positions which correspond to both sides of the pull tab 112 (seeFIG. 4o).

[0060] Here, it should be noted that the pair of tab lifting projections135 can be formed when forming the container cover 130 (that is, in apressing process). As an example of this, it is preferred that the shapeas shown in FIG. 4m or the shape as shown in FIG. 4n be used.

[0061] That is to say, referring to FIG. 4m, when the container cover130 is rotated, both sides of each tab lifting projection 135 are formedwith a pair of upward inclined portions 135 a in a manner such that thepull tab 122 is easily lifted by the pair of upward inclined portions135 a. Also, a middle portion of each tab lifting projection 135 isformed in the shape of a tab supporting portion 135 b which is flatlyformed between the pair of upward inclined portions 135 a in a mannersuch that the tab 122 is maintained in a lifted state.

[0062] Referring to FIG. 4n, both sides of each tab lifting projection135 are formed with a pair of upward inclined portions 135 c. Also, amiddle portion of each tab lifting projection 135 is formed in the shapeof a tab supporting portion 135 d which is depressed downward betweenthe pair of upward inclined portions 135 c in a manner such that thepull tab 122 is maintained in a lifted state.

[0063] Accordingly, by adopting the pair of tab lifting projections 135constructed as just mentioned above, as shown in FTG. 4 o, if rotatingforce is applied to two groups of protuberances 140 a and/or 140 b torotate the container cover 130, as the upward inclined portion 135 a or135 c of the tab lifting projection 135 is moved below the pull tab 122,the pull tab 122 is positioned on the tab supporting portion 135 b or135 d. And, in this way, a manipulating space for pulling upward thepull tab 122 and thereby opening the discharging hole 124 issufficiently secured.

[0064] Also, according to the present invention, as shown in FIGS. 4gthrough 4 r, the plurality of filtering holes 134 are defined uponforming the container cover 130 in a manner such that the filtering partwhich includes the plurality of filtering holes 134 projects upward fromthe plane of the container cover 130 and a press line 134 a is formedaround the filtering part.

[0065] Consequently, in the configuration of the filtering partincluding the plurality of filtering holes 134, as can be readily seenfrom FIG. 4r, even in the case that the container cover 130 is rotated,a lower surface of the filtering part is not brought into direct contactwith the upper surface of a body 110 of the beverage container 100.Also, in this configuration, in a state wherein the filtering part isaligned with the discharging hole 124 which is formed in the uppersurface of the beverage container 100, by depressing downward thefiltering part including the plurality of filtering holes 134, thefiltering part is fitted into the discharging hole 124. Therefore, dueto the fact that the lower surface of the filtering part is flushed witha lower end of the discharging hole 124, it is possible to drink thebeverage in a state wherein solid matters are not caught therebetween.

[0066] In the meanwhile, a person skilled in the art will readilyappreciate that a configuration and a size of the body of the containercover 130 according to the present invention can be changed, dependingupon a type of a beverage container which is used, without departingfrom the technical spirit of the present invention. Likewise, thepresent invention must not be understood to be limited with regard to athickness, a material and a color of the body of the container cover130. Instead, the contours and the numbers of the beverage dischargingopening 132, the plurality of filtering holes 134, the inner diameter ofthe straw insertion hole 136, and so forth can be diversely changed.

[0067]FIG. 5 is an exploded perspective view illustrating the beveragecontainer in which the container cover according to the presentinvention is coupled to the container end.

[0068] As shown in FIG. 5, the beverage container 100 according to thepresent invention has a construction wherein the container cover 130 isinstalled on the upper surface of the container end 120 which is coupledto an upper end of the body 110 of the beverage container 100. Thecontainer cover 130 is rotatably coupled between the upper surface ofthe container end 120 and the pull tab 122 in the course of forming thecontainer end 120 of the beverage container 100.

[0069]FIG. 6 is a block diagram illustrating an entire procedctre of amethod for mounting a container cover which is mountable to a beveragecontainer, in accordance with the embodiment of the present intention;FIG. 7 is a block diagram illustrating detailed processes of the methodfor mounting a container cover which is mountable to a beveragecontainer, in accordance with the embodiment of the present invention;and FIGS. 8a and 8 b are explanatory views used for explaining themethod for mounting a container cover which is mountable to a beveragecontainer, in accordance with the embodiment of the present invention.More particularly, FIGS. 8a and 8 b are views which are connected witheach other and schematically illustrate the processes as shown in FIG.7.

[0070] As shown in FIGS. 6 and 7, a method for mounting a containercover which is mountable to a beverage container in accordance with theembodiment of the present invention comprises a body forming process200, a container end forming process 300, a container end couplingprocess 400, a container cover forming process 500 and a container covercoupling process 600.

[0071] The body forming process 200 is a process for forming the body110 of the beverage container 100, in which the beverage is to beaccommodated. The container end forming process 300 is a process forforming the container end 120 which is to be coupled to the upper end ofthe body 110 formed by the body forming process 200 and to which thepull tab 122 for opening the discharging part and thereby defining thedischarging hole 124 is coupled. As described above, the discharginghole 124 allows the beverage to be discharged out of the beveragecontainer 100 therethrough.

[0072] The container cover forming process 500 is a process for formingthe container cover 130 which is composed of the body of substantiallythe disc-shaped configuration and is mounted to the upper surface of thecontainer end 120, with the body selectively formed with the beveragedischarging opening 132, the plurality of filtering holes 134 and thestraw insertion hole 136. The container cover coupling process 600 is aprocess for rotatably coupling the container cover 130 formed in thecontainer cover forming process 500, between the upper surface of thecontainer end 120 and the pull tab 122.

[0073] The body forming process 200, the container end forming process300 and the container cover forming process 500 are in consecutiveprocesses which may not be sequentially implemented. Therefore, the body110 of the beverage container 100, the container end 120 and thecontainer cover 130 are formed in their respective forming processes,depending upon process conditions such as a processing time, a space andthe like. Thereafter, while they are kept in stock, they can be used inthe container end coupling process 400 or in the container covercoupling process 600. The container cover coupling process 600 isperformed while the container end forming process 300 is implemented.

[0074] Moreover, the container cover forming process 500 is implementedthrough a press work using a press. The method according to the presentinvention further comprises a container cover loading process 700 forloading the container cover 130 which is formed in such a way, using aloading device (not shown), and for supplying the container cover 130onto the upper surface of the container end 120.

[0075] The method can further comprise an advertisement forming process900 for forming the advertisement such as the design, letters, and soforth, on the upper surface of the container cover 130 while thecontainer cover forming process 500 or the container cover loadingprocess 700 is implemented. The advertisement forming process 900 can beeffected using a printing technique in which the design and letters areprinted on the container cover 130, an affixing technique in which anadvertisement is affixed onto the container cover 130 or a formingtechnique in which the design and the letters are integrally formed onthe container cover 130. However, the advertisement forming process 900is not limited to the above-described techniques, and instead, can use adiversity of other techniques which are well known in the art. Also, theadvertisement forming process 900 must not be understood as beinglimitedly implemented only while implementing the container coverforming process 500 or the container cover loading process 700. Instead,the advertisement forming process 900 can be implemented under otherprocesses without limitation.

[0076] The loading device can comprise a conveyor system, a feedingrobot or the like.

[0077] On the other hand, describing the container end forming process300 in detail with reference to FIG. 7, the container end formingprocess 300 comprises a cutting step 310 for circularly cutting a thinmetal plate, (preferably, a metal plate which is wound in the form of acoil is mounted to a facility such as a coiler to enable a continuouscutting operation), which is coated with aluminum thereby to form acircular plate 312, an outer shell forming step 320 for forming an outershell 120 a of the container end 120 by bending upward an edge portionof the circular plate 312 which is cut in the cutting step 310, acompound applying step 330 for applying compound at a portion where theouter shell 120 a which is formed in the outer shell forming step 320 iscoupled to the upper end of the body 110 of the beverage container 100,a first step 342 for forming a protrusion 346 having a predeterminedsize, on a center portion of the circular plate 312 as shown in FIG. 8a,and a second step 314 for forming a pin seating part 348 on which acentral pin 126 for fastening the pull tab 122 is seated, by depressingdownward a center portion of the protrusion 346 which is formed in sucha way. The first step 342 and the second step 344 cooperativelyconstitute a pin seating part forming step 340.

[0078] The container end forming process 300 further comprises acontainer end surface forming step 350 for forming a schematic entirecontour of a container end surface on the circular plate 312, whichincludes a pair of tab fixing projections 354 for fixedly maintaining aposition of the pull tab 122 and the discharging part 352 to be formedwith the discharging hole 124, a score line forming step 360 for forminga score line 362 in a manner such that the score line 362 corresponds tothe contour of the discharging hole 124 in a manner such that thedischarging hole 124 through which the beverage is discharged out of thebeverage container 100 is formed as the discharging part 352 which isdefined in the container end surface forming step 350 is opened by thedepressing force of the pull tab 122, and a tab installing step 370 forloading and fastening the pull tab 122 on the pin seating part 348 whichis formed in the pin seating part forming step 340.

[0079] In the meanwhile, after implementing the compound applying step330 and the tab installing step 370, as shown in FIG. 7, an inspectingstep 390 for inspecting forming conditions at the respective steps andthereby for checking inferiority can be implemented. It is not necessarythat this inspecting step 390 be limitedly implemented only after thecompound applying step 330 and the tab installing step 370. Instead, theinspecting step 390 can be implemented before or after the variousprocesses and steps, as occasion demands.

[0080] Also, as shown in FIGS. 7, 8a and 8 b, after the compoundapplying step 330 and the pin seating part forming step 340 areimplemented, a design and letter forming step 392 for indicatingmanufacturing details 392a or forming advertising letters, design, andso forth, can be implemented.

[0081] In implementing the above-described container cover couplingprocess 600, before the pull tab 122 is loaded and coupled to thecontainer end 120, the container cover 130 can be loaded on thecontainer end 120 (see the path ‘a’ of FIG. 8b), or the pull tab 122 andthe container cover 130 are simultaneously loaded on the container end120. Thereupon, as the pull tab 122 is installed on the container end120 by the central pin 126, the container cover 130 is supported alongwith the pull tab 122 by the central pin 126 (see the path ‘b’ of FIG.8b). For example, as shown in FIG. 7, in implementing the tab installingstep 370, the container cover 130 is simultaneously loaded and installedalong with the pull tab 122 which is to be coupled to the container end120 by the central pin 126.

[0082] Also, fluctuation preventing means 800 are formed on thecontainer end 120 or on the container cover 130 in a manner such thatthe container cover 130 is fixedly maintained in place without beingfluctuated while the container cover 130 is loaded on the upper surfaceof the container end 120 and installed between the upper surface of thecontainer end 120 and the pull tab 122, and in a manner such that thetab fastening operation is smoothly performed upon implementing the tabinstalling step 370.

[0083] For example, as in tile container cover 130′ illustrated in FIG.8b (see the path ‘c’), the fluctuation preventing means 800 comprises apair of engaging grooves 810 which are formed in the container cover130′ (see FIG. 8b) in a manner such that the pair of tab fixingprojections 354 which are projectedly formed on the upper surface of thecontainer end 120 in the container end surface forming step 350 forenabling the pull tab 122 installed on the container end surface in thetab installing step 370 to be fastened without experiencing fluctuation,are engaged into the pair of engaging grooves 810, respectively. In thecase that the pair of engaging grooves 810 are formed in the containercover 130′ as described above, the pair of engaging grooves 810 can besimultaneously formed upon implementing a press work in the containercover forming process 500.

[0084] In other words, because the pair of tab fixing projections 354are engaged into the pair of engaging grooves 810, respectively, of thecontainer cover 130′, when installing the pull tab 122, the containercover 130 can be fixedly maintained without experiencing fluctuation .And, in a state wherein the container cover 130 is fixed, if the userpulls upward the pull tab 122 in order to drink the beverageaccommodated in the beverage container 100, as a distance between thepull tab 122 and the container end surface is lengthened, the containercover 130 is ready to be rotated.

[0085] In the container end forming process 300, if the tab installingstep 370 by which the pull tab 122 is installed, is completed, a packingand storing process 380 for packing and storing the container end 120 ina proper unit is effected.

[0086] In the meanwhile, the method for mounting a container covermountable to a beverage container is not limited to the method accordingto the above-described embodiment, and instead, can be variouslymodified without departing from the technical spirit of the presentinvention. Also, while it is explained in the above embodiment that thecylindrical metal container is used, the present invention must not beunderstood to be limited to this construction. Rather, the presentinvention can be applied to containers which have a variety of materialsand a diversity of configurations. In this regard, it is preferred thatmaterials for the container and the container cover be the same witheach other for promoting recycling. For example, if the beveragecontainer is made of aluminum, the container cover can also be made ofaluminum for facilitating material recycling. In accordance with anotherembodiment of the present invention, the beverage container and thecontainer cover can be made of paper.

[0087] Hereinafter, a method for mounting a container cover mountable toa beverage container, in accordance with another embodiment of thepresent invention will be described with reference to the attacheddrawings.

[0088]FIG. 9a is a block diagram illustrating an entire procedure of amethod for mounting a container cover which is mountable to a beveragecontainer, in accordance with another embodiment of the presentinvention; FIG. 9b is a block diagram illustrating detailed processes ofthe method for mounting a container cover which is mountable to abeverage container, in accordance with the embodiment of the presentinvention, as shown in FIG. 9a; and FIG. 10 is a schematic viewillustrating a course in which the container cover is mounted to thecontainer end, while implementing the method for mounting a containercover which is mountable to a beverage container, in accordance with theembodiment of the present invention, as shown in FIG. 9a.

[0089] In the method for mounting a container cover mountable to abeverage container in accordance with another embodiment of the presentinvention, as shown in FIG. 9a, the container end 120 is formed by thepreset container end forming process, and the container cover 130 isformed by the container cover forming process, for example, the pressworking process. At this time, the container cover 130 comprises thebody of substantially the disc-shaped configuration. The container cover130 has the beverage discharging opening 132, the plurality of filteringholes 134 and the straw insertion hole 136 which can be selectivelyformed in the body. The beverage discharging opening 132 is formed insuch a manner that it is communicated with the discharging hole 124which is formed by an opening action of the pull tab 122 mounted Lo thecontainer end 120 which is coupled to the upper end of the body 110 ofthe beverage container 100, thereby allowing the beverage accommodatedin the body 110 of the beverage container 100 to be discharged out ofthe beverage container 100. The plurality of filtering holes 134 areformed in a manner such that solid matters existing in the beveragecontainer 100 can be filtered thereby. The straw insertion hole 136 isformed to have the predetermined diameter in a manner such that thestraw can be inserted therethrough. The method in accordance with thisanother embodiment of the present invention comprises a container endloading step 1210 for loading the container end 120 and moving thecontainer end 120 in a predetermined direction; a container end sensingand aligning step 1220 for sensing and aligning in a predeterminedorientation the container end 120 which is moved by the container endloading step 1210; and a container cover inserting step 1230 forinserting the container cover 130 between the upper surface of thecontainer end 120 which is moved in an aligned state by the containerend sensing and aligning step 1220 and the pull tab 122.

[0090] As shown in FIGS. 9b and 10, the container cover inserting step1230 comprises a first sub-step 1232 of fixedly maintaining thecontainer end 120 which is moved, thereby to prevent the container end120 from fluctuating; a second sub-step 1234 of slantingly lifting thepull tab 122 at a predetermined angle, which is coupled to the upper endof the container end 120 which is fixedly maintained by the firstsub-step 1232; and a third sub-step 1236 of inserting the containercover 130 between the pull tab 122 which is lifted by the secondsub-step 1234 and the upper surface of the container end 120.

[0091] The second sub-step 1234 is, as shown in FIG. 10, implementedusing a proper tool which is inserted between the upper surface of thecontainer end 120 and the pull tab 122 to lift the pull tab 122, such asa jig A. Also, the container cover inserting step 1230 further comprisesthe sub-step of returning the jig A which is inserted in the secondsub-step 1234 to its original position after the container cover 130 isinserted between the container end 120 and the pull tab 122 in the thirdsub-step 1236. If the jig A is returned it its original position, as thepull tab 122 is also returned to its original position by its ownelasticity, the mounting of the container cover 130 between thecontainer end 120 and the pull tab 122 is completed.

[0092] The container end sensing and aligning step 1220 serves as a stepfor sensing and aligning the container end 120 in the predeterminedorientation and then feeding the container end 1.20 to the next step, toensure the fact that the container cover 130 is reliably insertedbetween the container end 120 and the pull tab 122 in the second andthird sub-steps 1234 and 1236 of the container cover inserting step1230. Namely, by the container end sensing and aligning step 1220,because the pull tab 122 which is coupled to the upper surface of thecontainer end 120, is aligned in the same predetermined direction, thesecond and third sub-steps 1234 and 1236 can be rapidly implementedusing the single. tool or the jig A, and it is not necessary toadditionally adjust a direction of the tool or the jig A.

[0093] Moreover, as shown in FIG. 9a, the method for mounting thecontainer cover according to the present invention, can further includean arranging and storing step 1240 for arranging and storing in apredetermined pattern container ends 120 each of which has the containercover 130 inserted between the pull tab 122 and itself by the containercover inserting step 1230.

[0094] On the other hand, as in the above-described method according tothe present invention, if the container cover 130 is mounted to thecontainer end 120, by implementing the step of mounting the containerend 120 to the body 110 of the beverage container 100 into which thebeverage is accommodated, the manufacturing of the beverage container100 is completed.

[0095]FIG. 11a is a block diagram illustrating an apparatus for mountinga container cover which is mountable to a beverage container, inaccordance with still another embodiment of the present invention; andFIG. 11b is a schematic plan view illustrating the apparatus formounting a container cover which is mountable to a beverage container,according to the embodiment of the present invention, as shown in FIG.11a.

[0096] As shown in FIGS. 11a and 11 b, an apparatus for mounting acontainer cover which is mountable to a beverage container, inaccordance with the embodiment of the present invention, functions tomount the container cover 130 to the upper surface of the container end120. At this time, the container cover 130 comprises the body ofsubstantially the disc-shaped configuration. The container cover 130 hasthe beverage discharging opening 132, the plurality of filtering holes134 and the straw insertion hole 136 which can be selectively formed inthe body. The beverage discharging opening 132 is formed in such amanner that it is communicated with the discharging hole 124 which isformed by an opening action of the pull tab 122 mounted to the containerend 120 which is coupled to the upper end of the body 110 of thebeverage container 100, thereby allowing the beverage accommodated inthe body 110 of the beverage container 100 to be discharged out of thebeverage container 100. The plurality of filtering holes 134 are formedin a manner such that solid matters existing in the beverage container100 can be filtered thereby. The straw insertion hole 136 is formed tohave the predetermined diameter in a manner such that the straw can beinserted therethrough. The apparatus for mounting a container coverwhich is mountable to a beverage container, in accordance with theembodiment of the present invention, comprises a container end loadingdevice 1300 for loading the container end 120 and moving the containerend 120 in a predetermined direction; a container end sensing andaligning device 1400 for sensing and aligning in a predeterminedorientation the container end 120 which is moved by the container endloading device 1300; a container cover inserting device 1500 forinserting the container cover 130 between the upper surface of thecontainer end 120 which is moved in an aligned state by the containerend sensing and aligning device 1400 and the pull tab 122; and acontainer end arranging and storing device 1600 for arranging andstoring in a predetermined pattern container ends 120 each of which hasthe container cover 130 inserted between the pull tab 122 and itself bythe container cover inserting device 1500.

[0097] As shown in FIG. 11b, the container end loading device 1300comprises a conveyor system which is capable of loading and feeding thecontainer end 120 when the container end 120 formed by the container endforming process is transferred therein. It is preferred that theconveyor system is configured in a manner such that a plurality offeeding columns 1310 each of which can feed a plurality of containerends 120, are arranged therein, in a state wherein they are spaced apartone from another by a predetermined distance. The drawing referencenumeral 1320 represents a driving device for driving the container endloading device 1300.

[0098] The container end sensing and aligning device 1400 comprises asensing section 1410 for sensing a configuration of the container end120 which is moved along its path; a memory section 1420 for storingimage data signals which correspond to the plurality of container ends120, respectively; a control section 1430 for receiving an image signalof the container end 120, which is sensed by the sensing section 1410,comparing the image signal with an image data signal of a correspondingcontainer end 120, which is stored in the memory section 1420, andcreating a direction adjusting signal when the image signal sensed bythe sensing section 1410 is different from the image data signal storedin the memory section 1420, thereby to enable an image signal which isthe same as the image data signal to be sensed by the sensing section1410; a direction adjustment driving section 1440 actuated by thedirection adjusting signal which is transmitted from the control section1430; and a direction adjusting jig section 1450 driven by the directionadjustment driving section 1440 for adjusting a direction of thecontainer end 120.

[0099] The sensing section 1410 is composed of, for example, an imagesensor for sensing a configuration of the container end 120. The sensingsection 1410 outputs an image signal which is obtained by sensing theconfiguration of the container end 120, to the control section 1430. Thecontrol section 1430 compares the image signal which is transmitted fromthe sensing section 1410, with the image data signal of thecorresponding container end 120, and creates the direction adjustingsignal when the image signal sensed by the sensing section 1410 isdifferent from the image data signal stored in the memory section 1420.Thereupon, the direction adjustment is effected by the directionadjustment driving section 1440 and the direction adjusting jig section1450, whereby the container cover inserting operation which is performedby the container cover inserting device 1500 can be reliablyimplemented. For example, the image sensor photographs a direction ofthe pull tab 122 which is coupled to the upper surface of the containerend 120. The direction which is photographed or imaged by the sensingsection 1410 is compared with the data direction of the pull tab 122which is stored in the memory section 1420, if the two direction are notcoincident with each other, the direction of the container end 120 isadjusted, whereby it is possible to feed the container ends 120 whichare always aligned in the same predetermined direction, into thecontainer cover inserting device 1500.

[0100] The sensing section 1410 should not be understood as beinglimitedly composed of the image sensor. Instead, the sensing section canbe composed of a proximity sensor.

[0101] The container cover inserting device 1500 comprises a containerend fixing section 1510 for fixedly maintaining the container end 120 ina manner such that it does not fluctuate; a tab lifting section 1520inserted between the upper surface of the container end 120 which isfixedly maintained by the container end fixing section 1510 and the pulltab 122 for slantingly lifting the pull tab 122 at the predeterminedangle, the tab lifting section 1520 being returned to its originalposition after the container cover 130 is inserted between the uppersurface of the container end 120 and the pull tab 122; and a containercover inserting section 1530 for loading and inserting the containercover 130 between the upper surface of the container end 120 and thepull tab 122 in a state wherein the pull tab 122 is lifted.

[0102] The container end fixing section 1510 can comprise a jig which isable to grasp both sides of the container end 120 or a robot arm whichis able to fix the container end 120, etc.

[0103] The tab lifting section 1520 can be constructed to have a shapeas represented by the drawing reference numeral A in FIG. 10, thereby toeffect lifting of the pull tab 122.

[0104] The container cover inserting section 1530 can comprise a varietyof jigs, robot arms, or the like, capable of grasping the containercover 130 which is formed by the container cover forming facility, forexample, the press and then transferred by the conveyor system, or isformed by the container cover forming facility and then received in astoring receptacle, inserting the container cover 130 between thecontainer end 120 and the pull tab 122, and then returning to itsoriginal position.

[0105] Hereinafter, operations of the apparatus for mounting a containercover mountable to a beverage container, will be described in detail.

[0106] As shown in FIGS. 11a and 11 b, after the container covers 130which are formed by the container cover forming process and transferredby the conveyor system, or are formed by the container cover formingprocess and received in the storing receptacle, are supplied onto anupper surface of the container end loading device 1300, the plurality ofcontainer ends 120 are fed at a predetermined speed along their paths.

[0107] While the container ends 120 are fed as described above, thesensing section 1410 of the container end sensing and aligning device1400 senses a configuration of the container end 120, creates an imagesignal for the configuration of the container end 120 and transmits theimage signal to the control section 1430.

[0108] The control section 1430 compares the image signal of theconfiguration of the container end 120 which is sensed by the sensingsection 1410, with the data signal for the configuration which is storedin the memory section 1420, creates the direction adjusting signal ifthe two signals are not the same, and transmits the direction adjustingsignal to the direction adjustment driving section 1440 thereby to drivethe direction adjustment jig section 1450. By this, the direction of thecontainer end 120 is adjusted to be the same as that which is stored inthe memory section 1420.

[0109] The container end 120 which is adjusted in its direction asdescribed above, is fed into the container cover inserting device 1500and then inserted between the upper surface of the container end 120 andthe pull tab 122. Describing this procedure more detail, in a statewherein the container end 120 is fixedly maintained by the container endfixing section 1510 not to be fluctuated, the tab lifting section 1520lifts the pull tab 122 which is installed on the upper surface of thecontainer end 120 by the predetermined angle. In this situation, thecontainer cover insertion section 1530 grasps the container cover 130which is formed by the container cover forming facility, for example,the press and then transferred by the conveyor system, or is formed bythe container cover forming facility and then received in the storingreceptacle, inserts the container cover 130 between the container end120 and the pull tab 122, and then returns to its original position. Bythis, as the pull tab 122 is also returned to its original position byits own elasticity, the mounting operation of the container cover 130 iscompleted.

[0110] The container ends 120 to which the container covers 130 aremounted, respectively, are arranged by the container end arranging andstoring device 1600 in the predetermined pattern and then received in astorage.

[0111] On the other hand, as the container end 120 to which thecontainer cover 130 is mounted, is coupled to the upper end of the body110 of the beverage container 100 in which the beverage is accommodated,the manufacturing of the beverage container 100 is completed.

[0112] As described above, the container cover mountable to a beveragecontainer and a mounting method and apparatus thereof according to thepresent invention provide advantages in that, since it is possible toselectively reclose with the container cover an opened discharging holedefined in a container end surface, entrance of foreign substances intothe beverage container is avoided. Also, because the container cover isformed with at least one filtering hole and a straw insertion hole, ahigher grade of satisfaction can be rendered to a user.
